To all whom it may concern:

Be it known that I, CI-IAnLns E. LINK, a citizen of the United States, residing at Remington, in the county of Hamilton and State of Ohio, have invented new and use ful Improvements in Decarbonizer Sprayers, of which the following is a specification.

This invention relates to a sprayer device, the general object of the invention being to provide means for spraying a carbon remover into the combustion chamber of an internal combustion motor, so as to reach all parts'of the walls of the chamber with the liquid, to soften the Carbon thereon with the minimum amount of fluid.

Another object of the invention is to so form the sprayer that the fluid will be mixed with a large amount of air and that the fluid will be forced from the device in small quantities so that the device will have to be operated for a considerable amount of time in order to discharge the fluid therein, thus avoiding waste of the fluid by ejecting too much fluid on each stroke 'of the sprayer.

A further object of the invention is to provide a number of nozzles so that the device can be used on different types of motors and on motors, the spark plug holes of which are difiicult of access.

This invention also consists in certain other features of construction and in the combination and arrangen'ient of the several parts, to be hereinafter fully described, illustrated. in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a sectional view through a cylinder of a motor showing how the invention is used.

Figure 2 is a longitudinal sectional view through the sprayer device.

Figure 3 is a longitudinal sectional view showing the sprayer provided with an attachment for use on motors, the openings of which are diflicult of access.

Seria1 No. 675.432.

Figure is a view, with parts in section,

of this tube.

Figure 6 is a view of a modified form of tube.

Figure 7 is a view of a form of nozzle which may be used with the device.

Figure 8 is a view of another form of nozzle.

Figure 9 is a sectional view showing a centrally arranged retainer tube and another form of nozzle.

Figure 10 is a sectional view of an extension pipe.

Figure 11 is a view of a nozzle 9.

In these views 1 indicates the cylinder of the sprayer pump, 2 the piston thereof and 3 the piston rod which is provided with the handle The piston is double acting so that on the up stroke it will produce a vacuum in the lower end of the cylinder and on the down stroke it will act to force the air and fluid through the tube This tube acts as a retainer for the fluid drawn into the cylinder on the up stroke of the piston as it extends an appreciable distance intothe lower end of the cylinder to form a trap for the fluid. If too much liquid is drawn into the cylinder so that the level thereof is above the upper end of the tube, this surplus liquid will flow out of the tube until the level is below the top of the tube. A very small hole 6 is formed in the tube just above the lower end of the cylinder so that some of the liquid. will be forced into the tube through this hole on the down stroke of the piston. This hole is so small, however, that but a small quantity of liquid will be discharged on each down stroke of the piston. I prefer to make the bottom of the piston in the form of a screw cap 7 through which the tube passes and to offset the tube from the center of the cap. I also bend the inner end of the tube as shown at 8 so that the tube will retain a certain amount. of liquid in the cylinder even though the cylinder is held horizontally or at an incline. The hole is made in the tube on the opposite side from the bend so that practically all the liquid in the cylinder can be forced through the hole for operating the device and while held in a. horizontal or inclined position. However, when the device is used on motors, the cylinders of which are vertical, the upper end of the tube may be straight, as shown at o in Figure 9v and said tube .may pass 7 through the center of the cap 7, as shown I 1n this figure.

The bent tube eccentrically arranged, is designed for use where the sorayer is used on motors, the cylinders of which are horizontally or inclinedly arranged, and on motors in which the spark plug holes are dilhoult of access. 7

A nozzle 9 is connected with the retainer tube 5 by the coupling 10 and I may provide a plurality'of nozzles. for use with the sprayer so that the properkind of nozzle can be used with the-device. The drawings show various kinds of nozzles which may i be used withthedevice, though, it will, of

course, be understood, that any desired type of nozzle can be used with the device. Figures l, 2, 3 and 9 shownozzles whlch will direct the stream upwardly while Figure 7 shows a nozzle which will direct the stream at practically rightangles from the device and Figure 8 shows nozzle for directing the stream downwardly at an angle. Of course, the nozzle most suitable for the motor upon which the device is being used,

will be attached to the device. In Figure 9 the nozzle is screwed directly upon the tube 5 while in the other figures the nozzle is intended to be connected with the tube by a coupling, such as shown at 10.

When necessary or desirable, an extension pipe 11, shown in Figure 10, may be connected with the retainer tube and have the nozzle attached thereto.

On motors which have the gas tanks arranged above their cylinder heads, which makes the spark plug holes difiicult of ac cess, an attachment such as shown atA in Figure 3 is used with the device. This attachment comprises a body 12 having a chamber 13 therein and through which passes a tube 14 which'is rotatably mounted in the body and which is held fluid-tight therein bymeans of the glands 15. That q. portion of the tube located in the chamber is provided with perforations 16, one of which is arranged at the bottom of the chamber and acts as admin for the chamher. This tube may be formed with slots 17 as well as the perforations, as shown in Figures 5 and 6., In this case the drain hole 16" is arranged quite a distance below the other holes. The body isprovided with a tubular part 18 which has its lower end in communication with the bottom of the chamber and its outer end threaded to receive the coupling 10 on the retainer tube- 5 of the device. The tube 14 is provided with a handle 19 so that it can be rotated and a nozzle of'any desired type is connected with the lower end of the tube by if the coupling 20.

With this attachment, the Ford type of tractor and similar motors, can be sprayed with this device by inserting the nozzle on the tube 14 of the attachment in the. spark plug hole and then operating the plunger of the spray pump to force liquid and air from the pump into the chamber of the attachment. from which the mixture will pass through the holes. in the tube 14,

through .the tube and out of the nozzle. By turning the tube by means of the handle 19 all parts of the combustion chamber will be sprayed. I

This attachment is also useful in spraying motors of the horizontaland'inclined types, as the attachmentcan be adjusted' 'and when the piston is operated a small.

amo-untof this liquid is forced through the hole 6 in thetube and mixes with the air forced through the tube by the piston and i this mixtureis sprayed upon the walls of the combustion chamber so as to soften the carbon thereon. By moving the device,

all parts of the combustion chamber are sprayed and due to the small quantity of fluid ejected on each stroke of the piston, a minimum amount of fluid is used for treating each cylinder.

VVhile'the invention is shown as a pump j sprayer, 1t w1ll, of course,-be understood 105 that it may be used on other types ofspray ers. For instance, it may be used on the.

typewhere a rubber bulb is utilized for prov dlng the pressure necessary to force the liquid from the container. The essential part of the invention comprises the re tainer tube and the small hole therein for causing the fluid to small quantities.

The device willeject the mixture of air and fluid in the form of a mist, so that pass from the device in all the walls of the combustion chamber will be coated with the mixture.-

Any kind of a liquid carbon remover can i be used with the device. I have found that 1 denatured alcohol is very effective as a carbon remover and the best time to spray the cylinder is at nightafter the motor has partially cooled off. The remover will act upon-the carbon during the night so that when the motor is started up in the mornmg, the softcarbon will be blown'out of the motor. The-motor should be sprayed vquite frequently and when this is done, the combustion chambers of the motor are kept 7 free of carbon and the expensive job of scraping carbon from the cylinders is eliminated.

It is thought from the foregoing description that'the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
